At the start of October, Jack Sheen’s experimental music ensemble An assembly embark on a brief three-date English tour including the world premieres of two brand-new, specially commissioned pieces and the London premiere of a third.

“An assembly are a group dedicated to contemporary and experimental music, installation and performance. Conceived as a large, open, and flexible group with no fixed line up, format or personnel, An assembly have appeared in many guises, tackling works from virtuosic ensemble scores to mass group readings, via text scores, graphic notation, long duration performances, one-on-one ASMR installations, physical performance, and wrestling. For this tour, An assembly presents an ambitious two-part programme of new works by emerging composers and artists.

“Field recordings and midi-instruments are internalised, vocalised and imitated by voices and instruments in Louis D’Heudieres‘ ‘Laughter Studies 6b’; four vocalists stand downstage from a small instrumental quintet, describing and imitating their own private soundtracks of synthesised tunes and field recordings, transmitted to them via earphones in a surreal and hysterical collision of subjectivities accompanied by angular melodies and midi-drum solos.

“Award-winning visual artist Rowland Hill continues this process of interpreting found material in a new film and performance commissioned by An assembly. Created as a response to Edwin Denby’s 1959 review of Stravinsky’s final ballet ‘Agon’, Hill uses Denby’s review and its relentless metaphors, references and precise visual shocks as a script for a new work, taking the linguistic articulation of a dance and returning it to a choreographed state through film, live performance and sound in a work which Jack Sheen irreverently describes as the “silliest piece I have ever commissioned.”

“The concert will culminate in the world premiere of ‘An assembly’ by Brussels-based composer Charlie Usher, a forty-five minute meditation on listening, hearing, and duration for large ensemble and audio. A constant wave of fourteen-second miniatures, ‘An assembly’ invites us to eavesdrop on real-time transcriptions of music Usher listened to while writing, and as the piece folds into itself, and unfolds away from us, we trace this vast new work into our evening.”

Dates below: note that the London concert is free, but you’ll need to book a space via a ticket system. Note also that there’s a more in-depth preview of this concert tour on Ben Harper’s ‘Boring Like A Drill‘ blog.

In the same week, avant-classical/experimental chamber evening Kammer Klang returns to London to start its own autumn series.

The main draw for the October opener is the British premiere of Matthew Shlomowitz’s ‘Lecture About Listening to Music’, 2017 performed by two members of Ensemble Nikel (pianist Antoine Françoise – this time on synthesizer – and saxophonist Patrick Stadler) and by singer Jessica Aszodi. A well-known interdisciplinary singer, Jessica has mastered an unusually wide vocal range: on this occasion, however, she’ll just be talking, delivering the lecture component as Antoine and Patrick traverse a range of musical ideas including unsettling atmospherics and repetition, quotes from 1980s mainstream pop and cerebrally playful and jazzy concepts.

Post-modernism aside, this is an upfront and accessible piece. It’s literally, a talk on how we, with our information-age sweep of unconscious and studied influences, access and process music in the present day (but with Matthew providing lengthy, sympathetic musical illustrations as well as the lecture text). Here’s an earlier performance: also featuring Antoine and Patrick, and with Matthew himself in the role of lecturer.

Kammer Klang’s programmer Lucy Railton will be performing ‘Harm’ by New York minimalist/microtonalist drone composer Phill Niblock; a 2003 drone piece sourced from cello. Here’s an earlier version, with the source tones performed by cellist Arne Deforce, to give you an idea…

The October Fresh Klang piece (performed by violinist and recent Goldsmiths music graduate Evie Hilyer-Ziegler) is Ryoko Akama’s ‘Reaction, for a string instrument’, composed this year. Ryoko’s pieces, sometimes released via text scores and conceived as much as performances as they are compositions, are attempts to create “listening situations that magnify silence, time and space… offer(ing) quiet temporal/spatial experiences.” A performer herself, she works with “tiny aural and visual occurrences that embody “almost nothing” aesthetics“: small items from which miniscule sounds can be coaxed and made microscopically purposeful. A peek at Ryoko’s homepage reveals delicate assemblages (everyday lab equipment, ancient pedal sewing machines, tin cans, glass bottles, kitchenware, paper balloons, woolen gloves) waiting to be played. As regards Evie’s violin interpretation, I reckon it’s fair to expect some very small, quiet violin playing: perhaps a fitful breath on the strings…

“Led by a core group of seven musicians, The Riot Ensemble programme a wide array of the new music from across the globe, connecting people to great contemporary music and collaborating with a prestigious roster of guest artists in musician-led and organised performances. One of the few emerging ensembles in the UK to regularly commission and perform music by international emerging composers, they present the young composers they commission alongside exciting and established music from Bach to Birtwistle.

“Venezuelan virtuoso pianist Clara Rodríguez joins forces with TangOpera Duo to mark the centenary of her compatriot, composer Antonio Estévez (1916-1988) with a concert showcasing his works for piano and voice as part of a vibrant programme of piano pieces by some of the giants of Latin American classical music, including the seminal Argentine composer Alberto Ginastera (Argentina) (1916-1983), who also celebrates his centenary this year.

“Antonio Estévez is one of the most important Venezuelan composers of the 20th century, known especially for his ‘Cantata criolla’ and ‘Mediodía en el llan’o, recorded by the Simón Bolívar Youth Orchestra in 2008. A leading light of the Parisian-Venezuelan avant garde, Estévez’s music stands out for its rare beauty and profound originality. In Clara Rodríguez, Estévez has a longstanding ambassador for his legacy – her successful campaign to establish his output on the ABRSM 2015-2016 exam syllabus saw his music performed by thousands of pianists in the UK.

Heard here alongside some of Latin America’s most famous composers, such as Villa-Lobos (Brazil) and Cervantes (Cuba), this event places Estévez firmly amongst the panoply of Latin America’s ‘great’ composers. If you are unfamiliar with his music, this programme will be a revelation.”
